Description

Technical Field

[0001] This utility model relates to the field of steel parts processing, and in particular to a high-precision drilling and tapping device for steel parts. Background Technology

[0002] In our daily lives, many metal products we encounter, such as door locks on furniture and parts for bicycles and cars, are largely made of steel. These steel parts often require drilling and tapping processes to function properly.

[0003] As living standards improve, people have increasingly higher requirements for the quality of various steel products in their daily lives. Whether it's household hardware or everyday transportation tools (such as bicycles and electric vehicles), consumers expect them to have greater durability and reliability, which poses new challenges to the precision of drilling and tapping of steel parts.

[0004] In some small factories and workshops, traditional semi-automatic drilling and tapping equipment is still in use. When drilling and tapping, these machines require manual operation of the clamps to hold and fix the steel parts. First, the two sides of the steel parts are clamped and fixed one by one, which is quite troublesome. Second, the clamps are usually fixed to the device with bolts. When processing steel parts of different shapes, they often need to be changed frequently to ensure clamping stability. However, changing bolted clamps requires turning the bolts back and forth, which takes a long time and affects work efficiency.

[0005] To address these issues, a high-precision drilling and tapping device for steel parts is proposed. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 2This utility model provides an embodiment of a high-precision drilling and tapping device for steel parts, including a processing table 1 for supporting the overall device. The upper surface of the processing table 1 is provided with a drilling and tapping device 2. The drilling and tapping device 2 is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The drilling and tapping device 2 is equipped with a drill bit and can perform drilling and tapping. The outer wall of the drilling and tapping device 2 is provided with a protective component, which can achieve a protective function and prevent the flying of waste chips during drilling and tapping. The front surface of the processing table 1 is provided with a fixing mechanism, which can clamp and fix steel parts of different shapes and sizes, ensuring the stability of the steel parts during drilling and tapping and ensuring the processing accuracy. The fixing mechanism includes a positioning component and a quick-release component.

[0035] Reference Figure 2 - Figure 4 The positioning component includes a motor 31, and a screw 32 is fixedly connected to the output shaft of the motor 31. Both the motor 31 and the screw 32 are existing technologies and can be implemented by those skilled in the art. As they are existing technologies, they will not be described in detail in this case. After the motor 31 is started, it can drive the screw 32 to rotate. The thread helix angle of the thread groove on the outer wall of the screw 32 is less than five degrees, which can achieve a self-locking effect. A slider 33 is slidably connected to the lower surface of the processing table 1. The slider 33 slides in the back-and-forth direction and is located on the center line of the lower surface of the processing table 1. A connecting plate 34 is hinged to the right surface of the slider 33, and a connecting block 35 is hinged to the right end of the connecting plate 34. When the slider 33 moves back and forth, it will squeeze the connecting plate 34 and thus drive the connecting block 35 laterally. The movable connecting plate 34 and connecting block 35 are provided in two sets, symmetrically distributed on the left and right sides of the center line of the slider 33. When the slider 33 moves, the connecting blocks 35 on both sides will move closer or open simultaneously. The quick-release assembly includes a clamping plate 41, which can be flexibly replaced to suit steel parts of different shapes. It can ensure the number of contact points during clamping and ensure clamping stability. The lower surface of the clamping plate 41 is fixedly connected to the insert block 42, and the upper surface of the connecting block 35 is provided with a slot 401. The insert block 42 and the slot 401 fit together. One end of the compression spring 44 is fixedly connected to the inner wall of the front side of the connecting block 35, and the other end of the compression spring 44 is fixedly connected to the locking block 43. The front surface of the insert block 42 is provided with a locking groove 402, and the locking block 43 and the locking groove 402 fit together.

[0036] Reference Figure 2 - Figure 4The motor 31 is mounted on the front surface of the processing table 1. The screw 32 passes through and is rotatably connected to the front surface of the processing table 1. The screw 32 passes through and is threadedly connected to the rear surface of the slider 33. When the screw 32 rotates, it will drive the slider 33 to move in the back-and-forth direction. The connecting block 35 passes through and is slidably connected to the upper surface of the processing table 1. The upper surface of the connecting block 35 is flush with the upper surface of the processing table 1. The insert block 42 is inserted into the inner wall of the slot 401. The outer wall of the insert block 42 fits against the inner wall of the slot 401. The locking block 43 is inserted into the inner wall of the slot 402. It can limit the insertion block 42. Under the influence of no continuous external force in the vertical direction, the insert block 42 can remain stable, thereby ensuring the stability of the clamping plate 41. The locking block 43 is slidably connected to the inner wall of the connecting block 35. The locking block 43 moves in the back-and-forth direction. When it moves forward, it will squeeze and compress the spring 44 to generate a reaction force. The rear end of the locking block 43 is set as an arc surface. When the arc surface is squeezed, the locking block 43 will move forward.

[0037] Reference Figure 1 , Figure 5 The protective component includes a sleeve 51, with one end of a connecting spring 52 fixedly connected to the inner wall of the top of the sleeve 51, and a protective sleeve 53 fixedly connected to the other end of the connecting spring 52. Both the sleeve 51 and the protective sleeve 53 surround the outside of the drill bit and can play a protective role. The sleeve 51 and the protective sleeve 53 are concentric. A ball bearing 54 is provided at the bottom of the protective sleeve 53. The ball bearing 54 can roll flexibly. The center of the ball bearing 54 is located inside the protective sleeve 53, which can reduce friction and ensure smooth sliding.

[0038] Reference Figure 1 , Figure 5 The sleeve 51 is set on the outer wall of the drilling and tapping device 2. The protective sleeve 53 is slidably connected to the lower surface of the sleeve 51 and moves longitudinally. When the lower surface of the protective sleeve 53 is squeezed, the protective sleeve 53 will move upward. When the protective sleeve 53 moves upward, it will squeeze the connecting spring 52 to generate a reaction force.

[0039] Working principle: Before using this device, first replace the clamping plate 41 with a matching one according to the shape of the steel part. When replacing, pull the clamping plate 41 upward, which will drive the insert block 42 to move upward. The upward-moving insert block 42 will squeeze the arc surface of the locking block 43. When the arc surface is squeezed, the locking block 43 will move forward and disengage from the locking groove 402, releasing the limitation on the insert block 42. At this time, the insert block 42 can be removed to complete the disassembly of the clamping plate 41. Then, take out the required clamping plate 41 and insert the insert block 42 into the slot 401. During the insertion process, the arc surface of the locking block 43 will be squeezed, the locking block 43 will move forward to release the obstruction, and will squeeze the compression spring 44 to generate a reaction force. When the insert block 42 is fully inserted, the locking groove 402 will be aligned with the locking block 43. The reaction force of the compression spring 44 will push the locking block 43 and the locking groove 402 to engage, limiting the insertion block 42 and the clamping plate 41 to ensure stability.

[0040] Then, the steel part requiring drilling and tapping is placed on the processing table 1. The motor 31 is then started, driving the screw 32 to rotate, which in turn moves the slider 33 forward, pulling the connecting plate 34 so that the connecting blocks 35 on both sides and the clamping plate 41 come together to clamp and fix the steel part. Once fixed, the drilling and tapping device 2 is started to drill and tap. During drilling and tapping, the ball bearing 54 contacts the upper surface of the steel part and pushes upwards against the protective sleeve 53, causing the protective sleeve 53 to retract into the sleeve 51 and release the obstruction. This completes the connection process. Under the influence of the elasticity of spring 52, the ball 54 will always be in contact with the surface of the steel part, ensuring that the protective sleeve 53 and sleeve 51 can block the flying debris and prevent the flying debris from injuring the workers. When the processing is completed, the drilling and tapping device 2 is turned off and the motor 31 is started to drive the screw 32 to rotate in the opposite direction. The reverse screw 32 will drive the slider 33 to move backward to press the connecting plate 34, so that the connecting blocks 35 and clamping plates 41 on both sides open to release the clamping of the steel part. Finally, the steel part can be removed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
